Patrick and Zheng,
I'm struggling to understand the bug. If the payload is uncompressed,
it can put a segment before coreboot in the bouncebuffer (this seems
to be the bug?). Then the loop needs to be re-run on the newly
split/added segment. If it is compressed, It will skip all of the
coreboot area and not allocate a segment before coreboot (put the
entire thing in the bounce buffer?).
Does this get back to the CONFIG_RAMBASE=0x00200000 on fam10?
